Preparation and properties of RE3+ doped luminescent co-polymer by solution copolymerization
Bonded type RE3+ doped luminescent co-polymer was synthesized by solution free radical copolymerization. The influence of charge sequence, monomers and co-polymerized method on properties and structures of the co-polymers was studied. The emission intensity of the co-polymers at different RE3+concentrations was tested. The results showed that the co-polymers of Eu-PSt and Eu-PMMA both had wid...

113. Polymer microneedles fabricated from alginate and hyaluronate for transdermal delivery of insulin
To reduce the inconvenient and painful of subcutaneous needle injection, the polymer microneedle patches that fabricated from modified alginate and hyaluronate were prepared for transdermal delivery of insulin. The as-prepared microneedles (MNs) exhibited excellent mechanical strength to penetrate the skin and good degradability to release loaded insulin. In vitro skin insertion capability was d...

Nucleation Effect of Thermotropic Liquid Crystalline Polymer on the Crystallization of Poly(epsilon-caprolactone)
Poly(ε-caprolactone) (PCL) has attracted much attention in recent years due to its good biodegradability
and biocompatibility. As a semicrystalline polymer, the fi nal properties of PCL strongly depend on its bulk
crystallization level. However, PCL shows a lower crystallization temperature and rate than other aliphatic
polyesters, which restricts its range of applications. To improve the crystal...

Magnetic Superhydrophobic Polymer Nanosphere Cage as a Framework for Miceller Catalysis in Biphasic Media
This study demonstrated the use of a magnetic superhydrophobic polymer nanosphere cage derived from a Pickering emulsion as a framework for miceller catalysis in biphasic media. We designed this system through the covalent stabilisation of active site (2,2,6,6-tetramethylpiperidine 1-oxyl)-grafted amphiphiles onto the magnetic hydrophobic core to form a micelle-like architecture and used it as a P...

40. Polymer electrolyte membranes based on cross-linked highly sulfonated co-polyimides
A novel diamine monomer 3,3''''''''-Bis(2,3,5,6-tetrafluoro-4-vinylphenoxy) biphenyl-4,4''''''''-diamine (TFVBPA) bearing double hydrophobic cross-linkable tetrafluorostyrol side-groups has been successfully synthesized via a nucleophilic substitution reaction. A series of cross-linked highly sulfonated co-polyimide (CSPIy-TFVBPAx) membranes with ion-exchange capacity (IEC) values ranging from 2.2...

Bottom-up fabrication of zwitterionic polymer brush on intraocular lens for improved biocompatibility
Intraocular lens (IOL) is an efficient implantable device commonly used for treating cataracts. However, bioadhesion of bacteria or residual lens epithelial cells on the IOL surface after surgery causes postoperative complications, such as endophthalmitis or posterior capsular opacification, and leads to loss of sight again. In the present study, zwitterionic polymer brushes were fabricated...

Thermo-responsive rheological behavior of borinic acid polymer in dilute solution.
In comparison with other boron containing polymers, the investigations on the borinic acid containing polymers have been mostly ignored in spite of their easy synthesis. Our previous studies indicate a borinic acid polymer (PBA) holds promising potential as a new type of stimuli-responsive polymer. However, the property investigations were mainly based on turbidity changes. Here, we report the r...

Properties of Polymer-Modified Mortar Using Silane as an Integral Additive
In the present paper, the addition of silane to improve the properties of mortar was
experimentally investigated. The morphology and microstructure of mortar were
investigated by using both scanning electron microscopy (SEM) and polarizing microscopy
(PM). The results show that silane significantly alters the microstructure of mortar, reduces
the crystallization, restricts the degree...

Studying Polymer Surfaces and Interfaces with Sum Frequency Generation Vibrational Spectroscopy
Usually a surface or an interface is well-defined with little diffusion from one side of the surface or interface to the other, with the length scale being on the order of one to several molecules. The molecular interactions on a surface or at an interface are thus dominated by short-range interactions. Various properties, such as wettability, reactivity, bi...
